1990 vs. 2026: Diese Reparatur mache ich NIE wieder!

🔧 Smartronik Repair Service (Advertisement) ➡️ https://www.smartronik-repair.de/ In this video, we take a close look at a 30-year-old Sega Game Gear retro console that suddenly won't turn on. What starts as a simple replacement of aged electrolytic capacitors quickly turns into a real repair nightmare. Besides leaking electrolyte, we find corroded solder joints, oxidized traces, and an internal short circuit on the mainboard, which almost derails the entire project. Join me step-by-step as I troubleshoot the power supply, audio, and video boards. We measure voltages, reconstruct damaged contacts with wire bridges, and get to the bottom of the mysterious, extremely dark display. Even when the original backlight (neon tube) is working again, the image remains lacking in contrast – until, after more than three hours of work, the true cause is revealed. Learn why standard repair kits are often insufficient for genuine layer damage and how crucial precise soldering and structural electronics troubleshooting are. The video culminates in an exciting functional test with a true classic game. A challenging repair full of hurdles, cold solder joints, and valuable insights for every electronics and retro enthusiast! ________________________________________ 📢 Transparency Note: This video contains self-promotion (referral to my website) and affiliate links.
